Embrace your power with the Volcanica Bra by Suyiyi, designed specifically for Stage 2 and Stage 3 teen girls who demand reliable support for intense sports like running, swimming, and jumping. As breasts develop and physical activity intensifies, this bra expertly balances professional shock absorption with a no-compression fit — perfect for growing bodies that need stability without restriction.
The secret lies in its innovative three-layer structure combining a shock absorption layer, a breathable ventilation layer, and a durable outer fabric. Unique waterdrop-shaped cutouts at the nipple area gently cradle the breast base while releasing the top, providing exceptional shock reduction while preventing uncomfortable compression.
Science-backed sizing supports growth stages:
-
Stage 2 (Approx. age 12-15): Underbust-to-overbust difference 5-10 cm; Lemon-sized or smaller bust; light cup padding recommended; moderate support.
-
Stage 3 (Approx. age 16-18): Underbust-to-overbust difference 10-15 cm; Peach-sized or larger bust; deep cup padding recommended; strong support.
Soft & Breathable:
-
Strategically zoned breathable mesh panels and arc-shaped ventilation holes keep sweat and heat away during high-intensity workouts.
-
Skin-friendly materials protect delicate, developing skin from irritation.
Professional Shock Absorption:

Triple-layer design with waterdrop cutouts at breast base stabilizes roots while releasing breast peaks for balanced shock reduction.
